For my case handling UIDeviceOrientationDidChangeNotification was not good solution as it is called more frequent and UIDeviceOrientation is not always equal to UIInterfaceOrientation because of (FaceDown, FaceUp).

I handle it using UIApplicationDidChangeStatusBarOrientationNotification:

//To add the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didChangeOrientation:)

//to remove the
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];

 ...

- (void)didChangeOrientation:(NSNotification *)notification
{
    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

    if (UIInterfaceOrientationIsLandscape(orientation)) {
        NSLog(@"Landscape");
    }
    else {
        NSLog(@"Portrait");
    }
}

There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:

• ondeviceorientation is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha, beta, gamma values on the event data supplied as the only argument to the function.

• onmozorientation is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x, y, z fields on the event data supplied as first argument.

• ondevicemotion is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration and accelerationIncludingGravity, which both have three fields for each axis: x, y, z

The "earthquake detecting" sample website uses a series of if statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt function:

if (window.DeviceOrientationEvent) {
    window.addEventListener("deviceorientation", function () {
        tilt([event.beta, event.gamma]);
    }, true);
} else if (window.DeviceMotionEvent) {
    window.addEventListener('devicemotion', function () {
        tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
    }, true);
} else {
    window.addEventListener("MozOrientation", function () {
        tilt([orientation.x * 50, orientation.y * 50]);
    }, true);
}

The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)

I had this problem in a DataFrame (df) created from an Excel-sheet with several internal header rows.

After cleaning out the internal header rows from df, the columns' values were of "non-null object" type (DataFrame.info()).

This code converted all numerical values of multiple columns to int64 and float64 in one go:

for i in range(0, len(df.columns)):
    df.iloc[:,i] = pd.to_numeric(df.iloc[:,i], errors='ignore')
    # errors='ignore' lets strings remain as 'non-null objects'

Existing answers did not work for me i just used $('.confirm').hide(). and it worked for me.

success: function(res) {
$('.confirm').hide()
swal("Deleted!", "Successfully deleted", "success")
setTimeout(function(){
window.location = res.redirect_url;
},700);

The difference can be illustrated by the following:

std::cout << std::endl;

is equivalent to

std::cout << '\n' << std::flush;

So,

• Use std::endl If you want to force an immediate flush to the output.
• Use \n if you are worried about performance (which is probably not the case if you are using the << operator).

I use \n on most lines.
Then use std::endl at the end of a paragraph (but that is just a habit and not usually necessary).

Contrary to other claims, the \n character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin and std::cout being special but still files (or file-like)).

So you want to split on spaces, and on commas and periods that aren't surrounded by numbers. This should work:

r" |(?<![0-9])[.,](?![0-9])"

If you're working in Episerver, or another MVC-based CMS, you may find that that particular controller name has already been claimed.

This happened to me when attempting to create a controller called FileUpload.

You can try this. :) simple solution!

=IF(ISNUMBER(MATCH(I1,E:E,0)),"TRUE","")

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:

Add-PSSnapin Microsoft.Sharepoint.Powershell

in the Powershell console.

I see some of the above answers are now a bit out of date. From my perspective, and I work with both Solr(Cloud and non-Cloud) and ElasticSearch on a daily basis, here are some interesting differences:

• Community: Solr has a bigger, more mature user, dev, and contributor community. ES has a smaller, but active community of users and a growing community of contributors
• Maturity: Solr is more mature, but ES has grown rapidly and I consider it stable
• Performance: hard to judge. I/we have not done direct performance benchmarks. A person at LinkedIn did compare Solr vs. ES vs. Sensei once, but the initial results should be ignored because they used non-expert setup for both Solr and ES.
• Design: People love Solr. The Java API is somewhat verbose, but people like how it's put together. Solr code is unfortunately not always very pretty. Also, ES has sharding, real-time replication, document and routing built-in. While some of this exists in Solr, too, it feels a bit like an after-thought.
• Support: there are companies providing tech and consulting support for both Solr and ElasticSearch. I think the only company that provides support for both is Sematext (disclosure: I'm Sematext founder)
• Scalability: both can be scaled to very large clusters. ES is easier to scale than pre-Solr 4.0 version of Solr, but with Solr 4.0 that's no longer the case.

For more thorough coverage of Solr vs. ElasticSearch topic have a look at https://sematext.com/blog/solr-vs-elasticsearch-part-1-overview/ . This is the first post in the series of posts from Sematext doing direct and neutral Solr vs. ElasticSearch comparison. Disclosure: I work at Sematext.

Here's a list of things that are worth checking:

Is Suhosin installed?

• How to check whether Suhosin is installed?

ini_set

• The format is important ini_set('memory_limit', '512'); // DIDN'T WORK ini_set('memory_limit', '512MB'); // DIDN'T WORK ini_set('memory_limit', '512M'); // OK - 512MB ini_set('memory_limit', 512000000); // OK - 512MB

When an integer is used, the value is measured in bytes. Shorthand notation, as described in this FAQ, may also be used.

http://php.net/manual/en/ini.core.php#ini.memory-limit

• Has php_admin_value been used in .htaccess or virtualhost files?

Sets the value of the specified directive. This can not be used in .htaccess files. Any directive type set with php_admin_value can not be overridden by .htaccess or ini_set(). To clear a previously set value use none as the value.

‘&&’ : - is a Logical AND operator produce a boolean value of true or false based on the logical relationship of its arguments.

For example: - Condition1 && Condition2

If Condition1 is false, then (Condition1 && Condition2) will always be false, that is the reason why this logical operator is also known as Short Circuit Operator because it does not evaluate another condition. If Condition1 is false , then there is no need to evaluate Condtiton2.

If Condition1 is true, then Condition2 is evaluated, if it is true then overall result will be true else it will be false.

‘&’ : - is a Bitwise AND Operator. It produces a one (1) in the output if both the input bits are one. Otherwise it produces zero (0).

For example:-

int a=12; // binary representation of 12 is 1100

int b=6; // binary representation of 6 is 0110

int c=(a & b); // binary representation of (12 & 6) is 0100

The value of c is 4.

I was searching for the iOS PCH file having the same problem, if you got here like me too, the solution that I've found is by clearing derived data; Close Simulator(s), go to xCode prefs -> locations -> go to the derived data file path, close xCode, delete the files in the derived data folder, re launch and cheers :)

I would return a character char instead of a string.

public static char getChar(int i) {
    return i<0 || i>25 ? '?' : (char)('A' + i);
}

Note: when the character decoder doesn't recognise a character it returns ?

I would use 'A' or 'a' instead of looking up ASCII codes.

I was getting project warning as "Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment". I removed the J2SE1.5 library and added new JRE System Library which resolved my problem

Bootstrap 2.3.x and later supports the dropdown-submenu..

<ul class="dropdown-menu">
            <li><a href="#">Login</a></li>
            <li class="dropdown-submenu">
                <a tabindex="-1" href="#">More options</a>

You can also do this in addition

import re
string='24234ww'
val = re.search('[a-zA-Z]+',string) 
val[0].isalpha() # returns True if the variable is an alphabet
print(val[0]) # this will print the first instance of the matching value

Also note that if variable val returns None. That means the search did not find a match

For Windows (7), the same folder is located at,

%APPDATA%\Subversion\auth

Type in the above in the Run(Win key + R) dialog box and hit Enter,

To check the existing username open the below file as a text file,

%APPDATA%\Subversion\auth\svn.simple\xxxxxxxxxx

This is an example from Angular2 docs of how you can create and use your own Observables :

The Service

import {Injectable} from 'angular2/core'
import {Subject}    from 'rxjs/Subject';
@Injectable()
export class MissionService {
  private _missionAnnouncedSource = new Subject<string>();
  missionAnnounced$ = this._missionAnnouncedSource.asObservable();

  announceMission(mission: string) {
    this._missionAnnouncedSource.next(mission)
  }
}

The Component

    import {Component}          from 'angular2/core';
    import {MissionService}     from './mission.service';

    export class MissionControlComponent {
      mission: string;

      constructor(private missionService: MissionService) {

        missionService.missionAnnounced$.subscribe(
          mission => {
            this.mission = mission;
          })
      }

      announce() {
        this.missionService.announceMission('some mission name');
      }
    }

I had the same issue and was able to resolve it by manually removing the MapFragment in the onDestroy() method of the Fragment class. Here is code that works and references the MapFragment by ID in the XML:

@Override
public void onDestroyView() {
    super.onDestroyView();
    MapFragment f = (MapFragment) getFragmentManager()
                                         .findFragmentById(R.id.map);
    if (f != null) 
        getFragmentManager().beginTransaction().remove(f).commit();
}

If you don't remove the MapFragment manually, it will hang around so that it doesn't cost a lot of resources to recreate/show the map view again. It seems that keeping the underlying MapView is great for switching back and forth between tabs, but when used in fragments this behavior causes a duplicate MapView to be created upon each new MapFragment with the same ID. The solution is to manually remove the MapFragment and thus recreate the underlying map each time the fragment is inflated.

I also noted this in another answer [1].

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

This worked for me, converts to nested JSON to easy to read YAML

    string JSONDeserialized {get; set;}
    public int indentLevel;

    private bool JSONDictionarytoYAML(Dictionary<string, object> dict)
    {
        bool bSuccess = false;
        indentLevel++;

        foreach (string strKey in dict.Keys)
        {
            string strOutput = "".PadLeft(indentLevel * 3) + strKey + ":";
            JSONDeserialized+="\r\n" + strOutput;

            object o = dict[strKey];
            if (o is Dictionary<string, object>)
            {
                JSONDictionarytoYAML((Dictionary<string, object>)o);
            }
            else if (o is ArrayList)
            {
                foreach (object oChild in ((ArrayList)o))
                {
                    if (oChild is string)
                    {
                        strOutput = ((string)oChild);
                        JSONDeserialized += strOutput + ",";
                    }
                    else if (oChild is Dictionary<string, object>)
                    {
                        JSONDictionarytoYAML((Dictionary<string, object>)oChild);
                        JSONDeserialized += "\r\n";  
                    }
                }
            }
            else
            {
                strOutput = o.ToString();
                JSONDeserialized += strOutput;
            }
        }

        indentLevel--;

        return bSuccess;

    }

usage

        Dictionary<string, object> JSONDic = new Dictionary<string, object>();
        JavaScriptSerializer js = new JavaScriptSerializer();

          try {

            JSONDic = js.Deserialize<Dictionary<string, object>>(inString);
            JSONDeserialized = "";

            indentLevel = 0;
            DisplayDictionary(JSONDic); 

            return JSONDeserialized;

        }
        catch (Exception)
        {
            return "Could not parse input JSON string";
        }

The first parameter is the String to encode; the second is the name of the character encoding to use (e.g., UTF-8).

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

I am using Linux and have nvm and working with more than 7 version of node As of my experience I experienced the same situation with my latest project (actually not hours but minutes as I can't wait hours because of hourly project :))

Disclaimer: don't try below option until you know how cache clean works

npm cache clean --force

and then all working fine for me so it's looks like sometimes npm's cache gets confused with different versions of Node.

Official documentation of Npm cache can be found here

Override service method like this:

protected void service(HttpServletRequest request, HttpServletResponse   response) throws ServletException, IOException {
        doPost(request, response);
}

And Voila!

I have added app.UseStaticFiles(); this code in my startup.cs than it is fixed

It would be nice if there were some way of turning off "throw on non-success code" but if you catch WebException you can at least use the response:

using System;
using System.IO;
using System.Web;
using System.Net;

public class Test
{
    static void Main()
    {
        WebRequest request = WebRequest.Create("http://csharpindepth.com/asd");
        try
        {
            using (WebResponse response = request.GetResponse())
            {
                Console.WriteLine("Won't get here");
            }
        }
        catch (WebException e)
        {
            using (WebResponse response = e.Response)
            {
                HttpWebResponse httpResponse = (HttpWebResponse) response;
                Console.WriteLine("Error code: {0}", httpResponse.StatusCode);
                using (Stream data = response.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    string text = reader.ReadToEnd();
                    Console.WriteLine(text);
                }
            }
        }
    }
}

You might like to encapsulate the "get me a response even if it's not a success code" bit in a separate method. (I'd suggest you still throw if there isn't a response, e.g. if you couldn't connect.)

If the error response may be large (which is unusual) you may want to tweak HttpWebRequest.DefaultMaximumErrorResponseLength to make sure you get the whole error.

My solution was to add a space between the $ and the {.

For example:

@Value("${project.ftp.adresse}")

becomes

@Value("$ {project.ftp.adresse}")

Swift 4:

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    var height = super.tableView(tableView, heightForRowAt: indexPath)
    if (indexPath.row == HIDDENROW) {
        height = 0.0
    }
    return height
}

but watch out for this....

Long nullLong = null;

preparedStatement.setLong( nullLong );

-thows null pointer exception-

because the protype is

setLong( long )   

NOT

setLong( Long )

nice one to catch you out eh.

IE had (has?) the onbeforeprint and onafterprint events: you could wait for that, but it would only work on IE (which may or may not be ok).

Alternatively, you could try and wait for the focus to return to the window from the print dialog and close it. Amazon Web Services does this in their invoice print dialogs: you hit the print button, it opens up the print-friendly view and immediately opens up the printer dialog. If you hit print or cancel the print dialog closes and then the print-friendly view immediately closes.

From Windows 10 version 1607, the limitation has been removed by setting a registry key

If you use Git Extensions GUI it can show you a graphical visualization of dangling commits if you check "View -> Show reflog references". This will show dangling commits in the tree, just like all other referenced ones. This way it is way easier to find what you are looking for.

See this image for demonstration. Commits C2, C3, C4, and C5 on the image are dangling but still visible.

Had this problem as well. If you do have the libraries, but still have this error, it may be a configuration error. Your server.xml may be missing the following line:

 <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

(Alternatively, it may be commented out). This <Listener>, like other listeners is a child of the top-level <Server>.

Without the <Listener> line, there's no attempt to load the APR library, so LD_LIBRARY_PATH and -Djava.library.path= settings are ignored.

Yes, this is a kind of inconsistency in the language.

The "=" in myarray = "abc"; is assignment (which won't work as the array is basically a kind of constant pointer), whereas in char myarray[4] = "abc"; it's an initialization of the array. There's no way for "late initialization".

You should just remember this rule.

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

If you are trying to execute your program/application from the command prompt. Just make sure to restart your cmd after you have changed the JAVA_HOME var. Very simple but easily missed sometimes.

For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin to the PATH. Use whatever directory you have this installed in.

Then you can run from any directory in command line:

httpd -k restart

The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?

It is just a predefined generic delegate. Using it you don't need to declare every delegate. There is another predefined delegate, Action<T, T2...>, which is the same but returns void.

Actually openssl command is a better tool than curl for checking and debugging SSL. Here is an example with openssl:

openssl s_client -showcerts -connect stackoverflow.com:443 < /dev/null

and < /dev/null is for adding EOL to the STDIN otherwise it hangs on the Terminal.

But if you liked, you can wrap some useful openssl commands with curl (as I did with curly) and make it more human readable like so:

# check if SSL is valid
>>> curly --ssl valid -d stackoverflow.com
Verify return code: 0 (ok)

O = Let's Encrypt

Mike Flynn's version did not work for me. Renaming C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Microsoft.TeamFoundation.Git.Provider.dll worked for me.

In case you need to exit Vim in easy mode (while using -y option) you can enter normal Vim mode by hitting Ctrl + L and then any of the normal exiting options will work.

just try this simple method: in controller:-

 public function index()
   {
        $data = array(
            'title' => 'Home',
            'otherData' => 'Data Here'
        );
        return view('front.landing')->with($data);
   }

And in you layout (app.blade.php) :

<title>{{ $title }} - {{ config('app.name') }} </title>

Thats all.

More generalized approach may be to merge PARSENAME and % operator. (as answered in two of the answers above)

Results as per 1st approach above by SQLMenace

select PARSENAME(0.001,1) 

Result: 001

select PARSENAME(0.0010,1) 

Result: 0010

select PARSENAME(-0.001,1)

Result: 001

select PARSENAME(-1,1)

Result: -1 --> Should not return integer part

select PARSENAME(0,1)

Result: 0

select PARSENAME(1,1)

Result: 1 --> Should not return integer part

select PARSENAME(100.00,1)

Result: 00

Results as per 1st approach above by Pavel Morshenyuk "0." is part of result in this case.

SELECT (100.0001 % 1)

Result: 0.0001

SELECT (100.0010 % 1)

Result: 0.0010

SELECT (0.0001 % 1)

Result: 0.0001

SELECT (0001 % 1)

Result: 0

SELECT (1 % 1)

Result: 0

SELECT (100 % 1)

Result: 0

Combining both:

SELECT PARSENAME((100.0001 % 1),1)

Result: 0001

SELECT PARSENAME((100.0010 % 1),1)

Result: 0010

SELECT PARSENAME((0.0001 % 1),1)

Result: 0001

SELECT PARSENAME((0001 % 1),1)

Result: 0

SELECT PARSENAME((1 % 1),1)

Result: 0

SELECT PARSENAME((100 % 1),1)

Result: 0

But still one issue which remains is the zero after the non zero numbers are part of the result (Example: 0.0010 -> 0010). May be one have to apply some other logic to remove that.

I noticed that if you run the unittest command line interface from your "src" directory, then imports work correctly without modification.

python -m unittest discover -s ../test

If you want to put that in a batch file in your project directory, you can do this:

setlocal & cd src & python -m unittest discover -s ../test

CREATE EVENT test_event_03
ON SCHEDULE EVERY 1 MINUTE
STARTS CURRENT_TIMESTAMP
ENDS CURRENT_TIMESTAMP + INTERVAL 1 HOUR
DO
   INSERT INTO messages(message,created_at)
   VALUES('Test MySQL recurring Event',NOW());

In database design, iIhighly recommend using Unixtime for consistency and indexing / search / comparison performance.

UNIX_TIMESTAMP() 

One can always convert to human readable formats afterwards, internationalizing as is individually most convenient.

FROM_ UNIXTIME (unix_timestamp, [format ])

Put this in your CSS:

white-space:nowrap;

Get more information here: http://www.w3.org/wiki/CSS/Properties/white-space

white-space

The white-space property declares how white space inside the element is handled.

Values

normal This value directs user agents to collapse sequences of white space, and break lines as necessary to fill line boxes.

pre This value prevents user agents from collapsing sequences of white space. Lines are only broken at newlines in the source, or at occurrences of "\A" in generated content.

nowrap This value collapses white space as for 'normal', but suppresses line breaks within text.

pre-wrap This value prevents user agents from collapsing sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

pre-line This value directs user agents to collapse sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

inherit Takes the same specified value as the property for the element's parent.

If you store the jQuery object in a variable you can do this:

var obj = $("#example").text('this\n has\n newlines');_x000D_
obj.html(obj.html().replace(/\n/g,'<br/>'));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<p id="example"></p>

If you prefer, you can also create a function to do this with a simple call, just like jQuery.text() does:

$.fn.multiline = function(text){_x000D_
    this.text(text);_x000D_
    this.html(this.html().replace(/\n/g,'<br/>'));_x000D_
    return this;_x000D_
}_x000D_
_x000D_
// Now you can do this:_x000D_
$("#example").multiline('this\n has\n newlines');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<p id="example"></p>

It's a textual encoding of binary data where the resultant text has nothing but letters, numbers and the symbols "+", "/" and "=". It's a convenient way to store/transmit binary data over media that is specifically used for textual data.

But why Base-64? The two alternatives for converting binary data into text that immediately spring to mind are:

1. Decimal: store the decimal value of each byte as three numbers: 045 112 101 037 etc. where each byte is represented by 3 bytes. The data bloats three-fold.
2. Hexadecimal: store the bytes as hex pairs: AC 47 0D 1A etc. where each byte is represented by 2 bytes. The data bloats two-fold.

Base-64 maps 3 bytes (8 x 3 = 24 bits) in 4 characters that span 6-bits (6 x 4 = 24 bits). The result looks something like "TWFuIGlzIGRpc3Rpb...". Therefore the bloating is only a mere 4/3 = 1.3333333 times the original.

Here are the type of keyboard in Swift 4.2

// UIKeyboardType
//
// Requests that a particular keyboard type be displayed when a text widget
// becomes first responder. 
// Note: Some keyboard/input methods types may not support every variant. 
// In such cases, the input method will make a best effort to find a close 
// match to the requested type (e.g. displaying UIKeyboardTypeNumbersAndPunctuation 
// type if UIKeyboardTypeNumberPad is not supported).
//
public enum UIKeyboardType : Int {


    case `default` // Default type for the current input method.

    case asciiCapable // Displays a keyboard which can enter ASCII characters

    case numbersAndPunctuation // Numbers and assorted punctuation.

    case URL // A type optimized for URL entry (shows . / .com prominently).

    case numberPad // A number pad with locale-appropriate digits (0-9, ?-?, ?-?, etc.). Suitable for PIN entry.

    case phonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).

    case namePhonePad // A type optimized for entering a person's name or phone number.

    case emailAddress // A type optimized for multiple email address entry (shows space @ . prominently).

    @available(iOS 4.1, *)
    case decimalPad // A number pad with a decimal point.

    @available(iOS 5.0, *)
    case twitter // A type optimized for twitter text entry (easy access to @ #)

    @available(iOS 7.0, *)
    case webSearch // A default keyboard type with URL-oriented addition (shows space . prominently).

    @available(iOS 10.0, *)
    case asciiCapableNumberPad // A number pad (0-9) that will always be ASCII digits.


    public static var alphabet: UIKeyboardType { get } // Deprecated
}

I think to add timestamp to every record and get the latest. In this situation you can get any ids, pack rows and other ops.

PHP way of getting text from span tag:

$spanText = $this->webDriver->findElement(WebDriverBy::xpath("//*[@id='specInformation']/tbody/tr[2]/td[1]/span[1]"))->getText();

<script type="text/javascript">
$(document).ready(function() {
    $('#upload').bind("click",function() 
    { 
        var imgVal = $('#uploadImage').val(); 
        if(imgVal=='') 
        { 
            alert("empty input file"); 

        } 
        return false; 

    }); 
});
</script> 

<input type="file" name="image" id="uploadImage" size="30" /> 
<input type="submit" name="upload" id="upload"  class="send_upload" value="upload" /> 

A few compilers (usually the ones for microcontrollers) has a special feature implemented within recognizing literal binary numbers by prefix "0b..." preceding the number, although most compilers (C/C++ standards) don't have such feature and if it is the case, here it is my alternative solution:

#define B_0000    0
#define B_0001    1
#define B_0010    2
#define B_0011    3
#define B_0100    4
#define B_0101    5
#define B_0110    6
#define B_0111    7
#define B_1000    8
#define B_1001    9
#define B_1010    a
#define B_1011    b
#define B_1100    c
#define B_1101    d
#define B_1110    e
#define B_1111    f

#define _B2H(bits)    B_##bits
#define B2H(bits)    _B2H(bits)
#define _HEX(n)        0x##n
#define HEX(n)        _HEX(n)
#define _CCAT(a,b)    a##b
#define CCAT(a,b)   _CCAT(a,b)

#define BYTE(a,b)        HEX( CCAT(B2H(a),B2H(b)) )
#define WORD(a,b,c,d)    HEX( CCAT(CCAT(B2H(a),B2H(b)),CCAT(B2H(c),B2H(d))) )
#define DWORD(a,b,c,d,e,f,g,h)    HEX( CCAT(CCAT(CCAT(B2H(a),B2H(b)),CCAT(B2H(c),B2H(d))),CCAT(CCAT(B2H(e),B2H(f)),CCAT(B2H(g),B2H(h)))) )

// Using example
char b = BYTE(0100,0001); // Equivalent to b = 65; or b = 'A'; or b = 0x41;
unsigned int w = WORD(1101,1111,0100,0011); // Equivalent to w = 57155; or w = 0xdf43;
unsigned long int dw = DWORD(1101,1111,0100,0011,1111,1101,0010,1000); //Equivalent to dw = 3745774888; or dw = 0xdf43fd28;

Disadvantages (it's not such a big ones):

• The binary numbers have to be grouped 4 by 4;
• The binary literals have to be only unsigned integer numbers;

Advantages:

• Total preprocessor driven, not spending processor time in pointless operations (like "?.. :..", "<<", "+") to the executable program (it may be performed hundred of times in the final application);
• It works "mainly in C" compilers and C++ as well (template+enum solution works only in C++ compilers);
• It has only the limitation of "longness" for expressing "literal constant" values. There would have been earlyish longness limitation (usually 8 bits: 0-255) if one had expressed constant values by parsing resolve of "enum solution" (usually 255 = reach enum definition limit), differently, "literal constant" limitations, in the compiler allows greater numbers;
• Some other solutions demand exaggerated number of constant definitions (too many defines in my opinion) including long or several header files (in most cases not easily readable and understandable, and make the project become unnecessarily confused and extended, like that using "BOOST_BINARY()");
• Simplicity of the solution: easily readable, understandable and adjustable for other cases (could be extended for grouping 8 by 8 too);

#pragma GCC diagnostic ignored "-Wformat"

Replace "-Wformat" with the name of your warning flag.

AFAIK there is no way to use push/pop semantics for this option.

I would like to refer a previous question, Because I have faced same problem and solved by this solution. First of all a constraint is always built with a Hash value in it's name. So problem is this HASH is varies in different Machine or Database. For example DF__Companies__IsGlo__6AB17FE4 here 6AB17FE4 is the hash value(8 bit). So I am referring a single script which will be fruitful to all

DECLARE @Command NVARCHAR(MAX)
     declare @table_name nvarchar(256)
     declare @col_name nvarchar(256)
     set @table_name = N'ProcedureAlerts'
     set @col_name = N'EmailSent'

     select @Command ='Alter Table dbo.ProcedureAlerts Drop Constraint [' + ( select d.name
     from 
         sys.tables t
         join sys.default_constraints d on d.parent_object_id = t.object_id
         join sys.columns c on c.object_id = t.object_id
                               and c.column_id = d.parent_column_id
     where 
         t.name = @table_name
         and c.name = @col_name) + ']'

    --print @Command
    exec sp_executesql @Command

It will drop your default constraint. However if you want to create it again you can simply try this

ALTER TABLE [dbo].[ProcedureAlerts] ADD DEFAULT((0)) FOR [EmailSent]

Finally, just simply run a DROP command to drop the column.

using str.replace(regex, $1);:

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;

if (str.match(regex)) {
    str = str.replace(regex, "$1" + "1" + "$2");
}

Edit: adaptation regarding the comment

If you want your JTextField to be focused when your GUI shows up, you can use this:

in = new JTextField(40);
f.addWindowListener( new WindowAdapter() {
    public void windowOpened( WindowEvent e ){
        in.requestFocus();
    }
}); 

Where f would be your JFrame and in is your JTextField.

you have to use the To_Date() function to convert the string to date ! http://www.techonthenet.com/oracle/functions/to_date.php

Make sure, that all of your class methods (updateVelocity, updatePosition, ...) take at least one positional argument, which is canonically named self and refers to the current instance of the class.

When you call particle.updateVelocity(), the called method implicitly gets an argument: the instance, here particle as first parameter.

Either of the following SQL will return all schema in Oracle DB.

1. select owner FROM all_tables group by owner;
2. select distinct owner FROM all_tables;

The 'mangler' in the above code sample was doing the equivalent of this:

bytesThing = stringThing.encode(encoding='UTF-8')

There are other ways to write this (notably using bytes(stringThing, encoding='UTF-8'), but the above syntax makes it obvious what is going on, and also what to do to recover the string:

newStringThing = bytesThing.decode(encoding='UTF-8')

When we do this, the original string is recovered.

Note, using str(bytesThing) just transcribes all the gobbledegook without converting it back into Unicode, unless you specifically request UTF-8, viz., str(bytesThing, encoding='UTF-8'). No error is reported if the encoding is not specified.

A subscription can be created and after taking the first emitted item destroyed. Pipe is a function that uses an Observable as its input and returns another Observable as output, while not modifying the first observable. Angular 8.1.0. Packages: "rxjs": "6.5.3", "rxjs-observable": "0.0.7"

  ngOnInit() {

    ...

    // If loading with previously saved value
    if (this.controlValue) {

      // Take says once you have 1, then close the subscription
      this.selectList.pipe(take(1)).subscribe(x => {
        let opt = x.find(y => y.value === this.controlValue);
        this.updateValue(opt);
      });

    }
  }

There is a easier way besides using the close() function. if you create a variable with the InfoWindow property it closes automatically when you open another.

var info_window;
var map;
var chicago = new google.maps.LatLng(33.84659, -84.35686);

function initialize() {
    var mapOptions = {
        center: chicago,
        zoom: 14,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

    info_window = new google.maps.InfoWindow({
        content: 'loading'
    )};

createLocationOnMap('Location Name 1', new google.maps.LatLng(33.84659, -84.35686), '<p><strong>Location Name 1</strong><br/>Address 1</p>');
createLocationOnMap('Location Name 2', new google.maps.LatLng(33.84625, -84.36212), '<p><strong>Location Name 1</strong><br/>Address 2</p>');

}

function createLocationOnMap(titulo, posicao, conteudo) {            
    var m = new google.maps.Marker({
        map: map,
        animation: google.maps.Animation.DROP,
        title: titulo,
        position: posicao,
        html: conteudo
    });            

    google.maps.event.addListener(m, 'click', function () {                
        info_window.setContent(this.html);
        info_window.open(map, this);
    });
}

Here is an email from Guido van Rossum in Python's dev list explaining why he choose not to return self on operations that affects the object and don't return a new one.

This comes from a coding style (popular in various other languages, I believe especially Lisp revels in it) where a series of side effects on a single object can be chained like this:

 x.compress().chop(y).sort(z)

which would be the same as

  x.compress()
  x.chop(y)
  x.sort(z)

I find the chaining form a threat to readability; it requires that the reader must be intimately familiar with each of the methods. The second form makes it clear that each of these calls acts on the same object, and so even if you don't know the class and its methods very well, you can understand that the second and third call are applied to x (and that all calls are made for their side-effects), and not to something else.

I'd like to reserve chaining for operations that return new values, like string processing operations:

 y = x.rstrip("\n").split(":").lower()

The only i was able to resolve this issue was to delete the local and git repo and create the same again at both ends. Works fine for now.

Use the token instead of the password (the token needs to have "api" scope for clone to be allowed):

git clone https://username:[email protected]/user/repo.git

Tested against 11.0.0-ee.

To clarify one point in @EdChum's answer, per the documentation, you can include the object columns by using df.describe(include='all'). It won't provide many statistics, but will provide a few pieces of info, including count, number of unique values, top value. This may be a new feature, I don't know as I am a relatively new user.

In "The C++ Programming Language, Third Edition by Bjarne Stroustrup", the nº1 must-read C++ book, he uses *.h. So I assume the best practice is to use *.h.

However, *.hpp is fine as well!

A recursive Python implementation:

def int2bin(n):
    return int2bin(n >> 1) + [n & 1] if n > 1 else [1] 

From the command line, you can type svn mv path1 path2. This will create an add and a delete operation, but there's not really a way around that - as far as I know - in Subversion.

You should only use extern template to force the compiler to not instantiate a template when you know that it will be instantiated somewhere else. It is used to reduce compile time and object file size.

For example:

// header.h

template<typename T>
void ReallyBigFunction()
{
    // Body
}

// source1.cpp

#include "header.h"
void something1()
{
    ReallyBigFunction<int>();
}

// source2.cpp

#include "header.h"
void something2()
{
    ReallyBigFunction<int>();
}

This will result in the following object files:

source1.o
    void something1()
    void ReallyBigFunction<int>()    // Compiled first time

source2.o
    void something2()
    void ReallyBigFunction<int>()    // Compiled second time

If both files are linked together, one void ReallyBigFunction<int>() will be discarded, resulting in wasted compile time and object file size.

To not waste compile time and object file size, there is an extern keyword which makes the compiler not compile a template function. You should use this if and only if you know it is used in the same binary somewhere else.

Changing source2.cpp to:

// source2.cpp

#include "header.h"
extern template void ReallyBigFunction<int>();
void something2()
{
    ReallyBigFunction<int>();
}

Will result in the following object files:

source1.o
    void something1()
    void ReallyBigFunction<int>() // compiled just one time

source2.o
    void something2()
    // No ReallyBigFunction<int> here because of the extern

When both of these will be linked together, the second object file will just use the symbol from the first object file. No need for discard and no wasted compile time and object file size.

This should only be used within a project, like in times when you use a template like vector<int> multiple times, you should use extern in all but one source file.

This also applies to classes and function as one, and even template member functions.

You could do this also with JavaScript.

I also had the same problem. Then I installed the zlib, still the problem remained the same. Then I added the following lines in my .bashrc and it worked. You should replace the path with your zlib installation path. (I didn't have root privileges).

You don't need any date-specific functions for this, it's just string manipulation:

var parts = fecha2.value.split('-');
var newdate = parts[1]+'-'+parts[2]+'-'+(parseInt(parts[0], 10)%100);

If anyone wants to generate PDFs on Android device, here is how to do it:

• http://sourceforge.net/projects/itext/ (library)
• http://www.vogella.de/articles/JavaPDF/article.html (tutorial)
• http://tutorials.jenkov.com/java-itext/image.html (images tutorial)

Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:

$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername

If you are using CSRF enter 'before'=>'csrf'

In your case Route::get('auth/login', ['before'=>'csrf','uses' => 'Auth\AuthController@getLogin', 'as' => 'login']);

You can use netcat for this.

nc ip port < /dev/null

connects to the server and directly closes the connection again. If netcat is not able to connect, it returns a non-zero exit code. The exit code is stored in the variable $?. As an example,

nc ip port < /dev/null; echo $?

will return 0 if and only if netcat could successfully connect to the port.

You can also use simple_format(@str) which removes malicious code. Read more here: http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-simple_format

The solution that worked for me in win and linux is the folling

// GET api/values
        [HttpGet("cifrado/{xml}")]
        public ActionResult<IEnumerable<string>> Cifrado(String xml)
        {
            String nombreXML = DateTime.Now.ToString("ddMMyyyyhhmmss").ToString();
            String archivo = "/app/files/"+nombreXML + ".XML";
            String comando = " --armor --recipient [email protected]  --encrypt " + archivo;
            try{
                System.IO.File.WriteAllText(archivo, xml);                
                //String comando = "C:\\GnuPG\\bin\\gpg.exe --recipient [email protected] --armor --encrypt C:\\Users\\Administrador\\Documents\\pruebas\\nuevo.xml ";
                ProcessStartInfo startInfo = new ProcessStartInfo() {FileName = "/usr/bin/gpg",  Arguments = comando }; 
                Process proc = new Process() { StartInfo = startInfo, };
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.RedirectStandardError = true;
                proc.Start();
                proc.WaitForExit();
                Console.WriteLine(proc.StandardOutput.ReadToEnd());
                return new string[] { "Archivo encriptado", archivo + " - "+ comando};
            }catch (Exception exception){
                return new string[] { archivo, "exception: "+exception.ToString() + " - "+ comando };
            }
        }

Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.

Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.

Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search"> as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.

Here is the needed Bootstrap markup.

<div class="position-relative">
    <i class="fa fa-search position-absolute"></i>
    <input class="form-control" type="search">
</div>

...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:

i {
    font-size: 1rem;
    color: #333;
    top: .75rem;
    left: .75rem
}

input {
    padding-left: 2.5rem;
}

You may have to fiddle with the values for top, left, and padding-left.

You could subscribe for the onchange event on the input field:

<input type="file" id="file" name="file" />

and then:

document.getElementById('file').onchange = function() {
    // fire the upload here
};

Markup

<asp:TextBox ID="txtDateOfBirth" runat="server" onkeydown="javascript:preventInput(event);" onpaste="return false;"
                                TabIndex="1">

Script

function preventInput(evnt) {
//Checked In IE9,Chrome,FireFox
if (evnt.which != 9) evnt.preventDefault();}

Check out the opensource Forge project. It provides a JavaScript TLS implementation, along with some Flash to handle the actual cross-domain requests:

http://github.com/digitalbazaar/forge/blob/master/README

In short, Forge will enable you to make XmlHttpRequests from a web page loaded over http to an https site. You will need to provide a Flash cross-domain policy file via your server to enable the cross-domain requests. Check out the blog posts at the end of the README to get a more in-depth explanation for how it works.

However, I should mention that Forge is better suited for requests between two different https-domains. The reason is that there's a potential MiTM attack. If you load the JavaScript and Flash from a non-secure site it could be compromised. The most secure use is to load it from a secure site and then use it to access other sites (secure or otherwise).

I am using XAMPP on Win 7 and 8.1 too...it start normally.

Did you try to check the services on Start > RUN > services.msc

Find the service: Apache 2.x. (right click) choose Properties. At form "Startup type" choose "Automatically" and Start the service on.

you should reset the PC and check out again.

Do the same with mySQL.

If you can not solve the problem, use XAMPP Panel to start it manually.

If you want to display the JSON data in well defined formate you can modify the code as:

file_put_contents($file, json_encode($json,TRUE));


$headers = array('http'=>array('method'=>'GET','header'=>'Content: type=application/json \r\n'.'$agent \r\n'.'$hash'));

$context=stream_context_create($headers);

$str = file_get_contents("list.txt",FILE_USE_INCLUDE_PATH,$context);

$str1=utf8_encode($str);

$str1=json_decode($str1,true);



foreach($str1 as $key=>$value)
{

    echo "key is: $key.\n";

    echo "values are: \t";
        foreach ($value as $k) {

        echo " $k. \t";
        # code...
    }
        echo "<br></br>";
        echo "\n";

}

As a supplement to the question and above answers there is also an important difference between plt.subplots() and plt.subplot(), notice the missing 's' at the end.

One can use plt.subplots() to make all their subplots at once and it returns the figure and axes (plural of axis) of the subplots as a tuple. A figure can be understood as a canvas where you paint your sketch.

# create a subplot with 2 rows and 1 columns
fig, ax = plt.subplots(2,1)

Whereas, you can use plt.subplot() if you want to add the subplots separately. It returns only the axis of one subplot.

fig = plt.figure() # create the canvas for plotting
ax1 = plt.subplot(2,1,1) 
# (2,1,1) indicates total number of rows, columns, and figure number respectively
ax2 = plt.subplot(2,1,2)

However, plt.subplots() is preferred because it gives you easier options to directly customize your whole figure

# for example, sharing x-axis, y-axis for all subplots can be specified at once
fig, ax = plt.subplots(2,2, sharex=True, sharey=True)

whereas, with plt.subplot(), one will have to specify individually for each axis which can become cumbersome.

I always do this to download the packages:

pip install --download /path/to/download/to_packagename

OR

pip install --download=/path/to/packages/downloaded -r requirements.txt

And when I want to install all of those libraries I just downloaded, I do this:

pip install --no-index --find-links="/path/to/downloaded/dependencies" packagename

OR

pip install --no-index --find-links="/path/to/downloaded/packages" -r requirements.txt

Update

Also, to get all the packages installed on one system, you can export them all to requirement.txt that will be used to intall them on another system, we do this:

pip freeze > requirement.txt

Then, the requirement.txt can be used as above for download, or do this to install them from requirement.txt:

pip install -r requirement.txt

Client side code: I had a requirement where my nodejs webserver should work as both server as well as client, so i added below code when i need it as client, It should work fine, i am using it and working fine for me!!!

const socket = require('socket.io-client')('http://192.168.0.8:5000', {
            reconnection: true,
            reconnectionDelay: 10000
          });
    
        socket.on('connect', (data) => {
            console.log('Connected to Socket');
        });
        
        socket.on('event_name', (data) => {
            console.log("-----------------received event data from the socket io server");
        });
    
        //either 'io server disconnect' or 'io client disconnect'
        socket.on('disconnect', (reason) => {
            console.log("client disconnected");
            if (reason === 'io server disconnect') {
              // the disconnection was initiated by the server, you need to reconnect manually
              console.log("server disconnected the client, trying to reconnect");
              socket.connect();
            }else{
                console.log("trying to reconnect again with server");
            }
            // else the socket will automatically try to reconnect
          });
    
        socket.on('error', (error) => {
            console.log(error);
        });

Your call to text() doesn't output anything because you inverted your x and your y:

plot(abs_losses, percent_losses, 
     main= "Absolute Losses vs. Relative Losses(in%)",
     xlab= "Losses (absolute, in miles of millions)",
     ylab= "Losses relative (in % of January´2007 value)",
     col= "blue", pch = 19, cex = 1, lty = "solid", lwd = 2)

text(abs_losses, percent_losses, labels=namebank, cex= 0.7)

Now if you want to move your labels down, left, up or right you can add argument pos= with values, respectively, 1, 2, 3 or 4. For instance, to place your labels up:

 text(abs_losses, percent_losses, labels=namebank, cex= 0.7, pos=3)

You can of course gives a vector of value to pos if you want some of the labels in other directions (for instance for Goldman_Sachs, UBS and Société_Generale since they are overlapping with other labels):

 pos_vector <- rep(3, length(namebank))
 pos_vector[namebank %in% c("Goldman_Sachs", "Societé_Generale", "UBS")] <- 4
 text(abs_losses, percent_losses, labels=namebank, cex= 0.7, pos=pos_vector)

I recently had a similar problem in latest Eclipse (Kepler) and fixed it by disabling the option "Honour all XML schema locations" in Preferences > XML > XML Files > Validation. It disables validation for references to the same namespaces that point to different schema locations, only taking the first found generally in the XML file being validated. This option comes from the Xerces library.

You can use various css-resets as you need, normal and use in css

 html
 {
  margin: 0px;
 padding: 0px;
 }

body

margin: 0px;
padding: 0px;
}

list1 = list1.stream().filter(str1-> 
        list2.stream().map(x->x.getStr()).collect(Collectors.toSet())
        .contains(str1)).collect(Collectors.toList());

This may work more efficient.

In response to Mike B, I prefer to use 'class' as, within a template, 'typename' has an overloaded meaning, but 'class' does not. Take this checked integer type example:

template <class IntegerType>
class smart_integer {
public: 
    typedef integer_traits<Integer> traits;
    IntegerType operator+=(IntegerType value){
        typedef typename traits::larger_integer_t larger_t;
        larger_t interm = larger_t(myValue) + larger_t(value); 
        if(interm > traits::max() || interm < traits::min())
            throw overflow();
        myValue = IntegerType(interm);
    }
}

larger_integer_t is a dependent name, so it requires 'typename' to preceed it so that the parser can recognize that larger_integer_t is a type. class, on the otherhand, has no such overloaded meaning.

That... or I'm just lazy at heart. I type 'class' far more often than 'typename', and thus find it much easier to type. Or it could be a sign that I write too much OO code.

I have encoding problems with XMLFilter solution, so I made XMLStreamReader to ignore namespaces:

class XMLReaderWithoutNamespace extends StreamReaderDelegate {
    public XMLReaderWithoutNamespace(XMLStreamReader reader) {
      super(reader);
    }
    @Override
    public String getAttributeNamespace(int arg0) {
      return "";
    }
    @Override
    public String getNamespaceURI() {
      return "";
    }
}

InputStream is = new FileInputStream(name);
XMLStreamReader xsr = XMLInputFactory.newFactory().createXMLStreamReader(is);
XMLReaderWithoutNamespace xr = new XMLReaderWithoutNamespace(xsr);
Unmarshaller um = jc.createUnmarshaller();
Object res = um.unmarshal(xr);

There are chances that you might end up with Scientific Number when you convert Integer to Str... safer way is

SET @ActualWeightDIMS = STR(@Actual_Dims_Width); OR Select STR(@Actual_Dims_Width) + str(@Actual_Dims_Width)

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

Just an update.

If the ticked answer is working fine for you but it shows nothing when the search text is empty. Here is the solution:

private class ItemFilter extends Filter {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        
        String filterString = constraint.toString().toLowerCase();
        
        FilterResults results = new FilterResults();

        if(constraint.length() == 0)
        {
            results.count = originalData.size();
            results.values = originalData;
        }else {

        
        final List<String> list = originalData;

        int count = list.size();
        final ArrayList<String> nlist = new ArrayList<String>(count);

        String filterableString ;
        
        for (int i = 0; i < count; i++) {
            filterableString = list.get(i);
            if (filterableString.toLowerCase().contains(filterString)) {
                nlist.add(filterableString);
            }
        }
        
        results.values = nlist;
        results.count = nlist.size();
     }
        return results;
    }

    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        filteredData = (ArrayList<String>) results.values;
        notifyDataSetChanged();
      }

   }

For any query comment below

$suppress_localhost = false;

This did the trick for me.

I prefer the style

An inner class cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?".

as u said here inner class cannot be static... i found the below code which is being given static....reason? or which is correct....

Yes, there is nothing in the semantics of a static nested type that would stop you from doing that. This snippet runs fine.

    public class MultipleInner {
        static class Inner {
        }   
    public static void main(String[] args) {
        for (int i = 0; i < 100; i++) {
            new Inner();
        }
    }
}

this is a code posted in this website...

for the question---> Can a Static Nested Class be Instantiated Multiple Times?

answer was--->

Now, of course the nested type can do its own instance control (e.g. private constructors, singleton pattern, etc) but that has nothing to do with the fact that it's a nested type. Also, if the nested type is a static enum, of course you can't instantiate it at all.

But in general, yes, a static nested type can be instantiated multiple times.

Note that technically, a static nested type is not an "inner" type.

An IDE is an integrated development environment - a suped-up text editor with additional support for developing (such as forms designers, resource editors, etc), compiling and debugging applications. e.g Eclipse, Visual Studio.

A Library is a chunk of code that you can call from your own code, to help you do things more quickly/easily. For example, a Bitmap Processing library will provide facilities for loading and manipulating bitmap images, saving you having to write all that code for yourself. Typically a library will only offer one area of functionality (processing images or operating on zip files)

An API (application programming interface) is a term meaning the functions/methods in a library that you can call to ask it to do things for you - the interface to the library.

An SDK (software development kit) is a library or group of libraries (often with extra tool applications, data files and sample code) that aid you in developing code that uses a particular system (e.g. extension code for using features of an operating system (Windows SDK), drawing 3D graphics via a particular system (DirectX SDK), writing add-ins to extend other applications (Office SDK), or writing code to make a device like an Arduino or a mobile phone do what you want). An SDK will still usually have a single focus.

A toolkit is like an SDK - it's a group of tools (and often code libraries) that you can use to make it easier to access a device or system... Though perhaps with more focus on providing tools and applications than on just code libraries.

A framework is a big library or group of libraries that provides many services (rather than perhaps only one focussed ability as most libraries/SDKs do). For example, .NET provides an application framework - it makes it easier to use most (if not all) of the disparate services you need (e.g. Windows, graphics, printing, communications, etc) to write a vast range of applications - so one "library" provides support for pretty much everything you need to do. Often a framework supplies a complete base on which you build your own code, rather than you building an application that consumes library code to do parts of its work.

There are of course many examples in the wild that won't exactly match these descriptions though.

Please check your /etc/yum.conf file, maybe it is exclude php packages.

You should remove php* from this line so you can download php-* packages:

exclude= courier* dovecot* exim* filesystem httpd* mod_ssl* mydns* php*

It's seems your server having some scripts like cPanel

It seems things were designed to avoid developers to se the root user, a better solution would be:

sudo mysql -u root

Then create a normal user, set a password, then use that user to work.

create user 'user'@'localhost' identified by 'user1234';
grant all on your_database.* to 'user'@'localhost';
select host, user from mysql.user;

Then try to access:

mysql -u user -p

Boom!

Security note: Disabling security checks is dangerous and should be avoided

You can disable security checks globally for all requests of the default client:

package main

import (
    "fmt"
    "net/http"
    "crypto/tls"
)

func main() {
    http.DefaultTransport.(*http.Transport).TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
    _, err := http.Get("https://golang.org/")
    if err != nil {
        fmt.Println(err)
    }
}

You can disable security check for a client:

package main

import (
    "fmt"
    "net/http"
    "crypto/tls"
)

func main() {
    tr := &http.Transport{
        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    }
    client := &http.Client{Transport: tr}
    _, err := client.Get("https://golang.org/")
    if err != nil {
        fmt.Println(err)
    }
}

In my case I had a cherry pick that produce a number of Merge Conflicts, so I decide to not complete the cherry pick. I discarded all my changes. Doing so put me into a state where I received the following error:

You have not concluded your merge (MERGE_HEAD exists

To fix the issue I performed the following git command which fixed the problem.

git cherry-pick --abort

I originally found a CSS way to bypass this when using the Cycle jQuery plugin. Cycle uses JavaScript to set my slide to overflow: hidden, so when setting my pictures to width: 100% the pictures would look vertically cut, and so I forced them to be visible with !important and to avoid showing the slide animation out of the box I set overflow: hidden to the container div of the slide. Hope it works for you.

UPDATE - New Solution:

Original problem -> http://jsfiddle.net/xMddf/1/ (Even if I use overflow-y: visible it becomes "auto" and actually "scroll".)

#content {
    height: 100px;
    width: 200px;
    overflow-x: hidden;
    overflow-y: visible;
}

The new solution -> http://jsfiddle.net/xMddf/2/ (I found a workaround using a wrapper div to apply overflow-x and overflow-y to different DOM elements as James Khoury advised on the problem of combining visible and hidden to a single DOM element.)

#wrapper {
    height: 100px;
    overflow-y: visible;
}
#content {
    width: 200px;
    overflow-x: hidden;
}

Supplementing the answer by p.s.w.g, here are three other ways of achieving this using lodash 4.17.5, without using _.includes():

Say you want to add object entry to an array of objects numbers, only if entry does not exist already.

let numbers = [
    { to: 1, from: 2 },
    { to: 3, from: 4 },
    { to: 5, from: 6 },
    { to: 7, from: 8 },
    { to: 1, from: 2 } // intentionally added duplicate
];

let entry = { to: 1, from: 2 };

/* 
 * 1. This will return the *index of the first* element that matches:
 */
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) });
// output: 0


/* 
 * 2. This will return the entry that matches. Even if the entry exists
 *    multiple time, it is only returned once.
 */
_.find(numbers, (o) => { return _.isMatch(o, entry) });
// output: {to: 1, from: 2}


/* 
 * 3. This will return an array of objects containing all the matches.
 *    If an entry exists multiple times, if is returned multiple times.
 */
_.filter(numbers, _.matches(entry));
// output: [{to: 1, from: 2}, {to: 1, from: 2}]

If you want to return a Boolean, in the first case, you can check the index that is being returned:

_.findIndex(numbers, (o) => { return _.isMatch(o, entry) }) > -1;
// output: true

One case you check that nginx hold on 80 number port in system by default , check if you have any server like as apache or anything exist on system that block 80 number port thats the problem occurred.

1 .You change port number on nginx by this way,

sudo vim /etc/nginx/sites-available/default

Change 80 to 81 or anything,

2. Check everything is ok by ,

sudo nginx -t

3. Restart server

sudo service nginx start

4. Check the status of nginx:

sudo service nginx status

Hope that will work

A weak entity is the entity which can't be fully identified by its own attributes and takes the foreign key as an attribute (generally it takes the primary key of the entity it is related to) in conjunction.

Examples

The existence of rooms is entirely dependent on the existence of a hotel. So room can be seen as the weak entity of the hotel.
Another example is the
bank account of a particular bank has no existence if the bank doesn't exist anymore.

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =

Use Thread.sleep(1000);

1000 is the number of milliseconds that the program will pause.

try
{
    Thread.sleep(1000);
}
catch(InterruptedException ex)
{
    Thread.currentThread().interrupt();
}

From the Android Docs -

onLongClick()

From View.OnLongClickListener. This is called when the user either touches and holds the item (when in touch mode), or focuses upon the item with the navigation-keys or trackball and presses and holds the suitable "enter" key or presses and holds down on the trackball (for one second).

onTouch()

From View.OnTouchListener. This is called when the user performs an action qualified as a touch event, including a press, a release, or any movement gesture on the screen (within the bounds of the item).

As for the "moving happens even when I touch" I would set a delta and make sure the View has been moved by at least the delta before kicking in the movement code. If it hasn't been, kick off the touch code.

In order to avoid this kind of ClassCastException, if you have:

class A
class B extends A

You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:

public B(A a) {
    super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
    // If B class has more attributes, then you would initilize them here
}

Update: Corrected map rendering algorithm, added more illustrations, changed formating.

Perhaps the advantage for the "zig-zag" technique for mapping the tiles to the screen can be said that the tile's x and y coordinates are on the vertical and horizontal axes.

"Drawing in a diamond" approach:

By drawing an isometric map using "drawing in a diamond", which I believe refers to just rendering the map by using a nested for-loop over the two-dimensional array, such as this example:

tile_map[][] = [[...],...]

for (cellY = 0; cellY < tile_map.size; cellY++):
    for (cellX = 0; cellX < tile_map[cellY].size cellX++):
        draw(
            tile_map[cellX][cellY],
            screenX = (cellX * tile_width  / 2) + (cellY * tile_width  / 2)
            screenY = (cellY * tile_height / 2) - (cellX * tile_height / 2)
        )

Advantage:

The advantage to the approach is that it is a simple nested for-loop with fairly straight forward logic that works consistently throughout all tiles.

Disadvantage:

One downside to that approach is that the x and y coordinates of the tiles on the map will increase in diagonal lines, which might make it more difficult to visually map the location on the screen to the map represented as an array:

However, there is going to be a pitfall to implementing the above example code -- the rendering order will cause tiles that are supposed to be behind certain tiles to be drawn on top of the tiles in front:

In order to amend this problem, the inner for-loop's order must be reversed -- starting from the highest value, and rendering toward the lower value:

tile_map[][] = [[...],...]

for (i = 0; i < tile_map.size; i++):
    for (j = tile_map[i].size; j >= 0; j--):  // Changed loop condition here.
        draw(
            tile_map[i][j],
            x = (j * tile_width / 2) + (i * tile_width / 2)
            y = (i * tile_height / 2) - (j * tile_height / 2)
        )

With the above fix, the rendering of the map should be corrected:

"Zig-zag" approach:

Advantage:

Perhaps the advantage of the "zig-zag" approach is that the rendered map may appear to be a little more vertically compact than the "diamond" approach:

Disadvantage:

From trying to implement the zig-zag technique, the disadvantage may be that it is a little bit harder to write the rendering code because it cannot be written as simple as a nested for-loop over each element in an array:

tile_map[][] = [[...],...]

for (i = 0; i < tile_map.size; i++):
    if i is odd:
        offset_x = tile_width / 2
    else:
        offset_x = 0

    for (j = 0; j < tile_map[i].size; j++):
        draw(
            tile_map[i][j],
            x = (j * tile_width) + offset_x,
            y = i * tile_height / 2
        )

Also, it may be a little bit difficult to try to figure out the coordinate of a tile due to the staggered nature of the rendering order:

Note: The illustrations included in this answer were created with a Java implementation of the tile rendering code presented, with the following int array as the map:

tileMap = new int[][] {
    {0, 1, 2, 3},
    {3, 2, 1, 0},
    {0, 0, 1, 1},
    {2, 2, 3, 3}
};

The tile images are:

• tileImage[0] -> A box with a box inside.
• tileImage[1] -> A black box.
• tileImage[2] -> A white box.
• tileImage[3] -> A box with a tall gray object in it.

A Note on Tile Widths and Heights

The variables tile_width and tile_height which are used in the above code examples refer to the width and height of the ground tile in the image representing the tile:

Using the dimensions of the image will work, as long as the image dimensions and the tile dimensions match. Otherwise, the tile map could be rendered with gaps between the tiles.

If you are using underscore you can go the functional route

a = ['foo', 'foo', 'bar'];

var results = _.reduce(a,function(counts,key){ counts[key]++; return counts },
                  _.object( _.map( _.uniq(a), function(key) { return [key, 0] })))

so your first array is

_.keys(results)

and the second array is

_.values(results)

most of this will default to native javascript functions if they are available

demo : http://jsfiddle.net/dAaUU/

Your code would be like this:

int *p = (int *)0x28ff44;

int needs to be the type of the object that you are referencing or it can be void.

But be careful so that you don't try to access something that doesn't belong to your program.

If your TextView has fixed width, alternative solution can be to create a View which will look like an underline and position it right below your TextView.

<RelativeLayout
   android:layout_width="match_parent"
   android:layout_height="match_parent">

        <TextView
            android:id="@+id/myTextView"
            android:layout_width="20dp"
            android:layout_height="wrap_content"/>

        <View
            android:layout_width="20dp"
            android:layout_height="1dp"
            android:layout_below="@+id/myTextView"
            android:background="#CCCCCC"/>
</RelativeLayout>

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

var b = String(stringInterpolationSegment: a)

This works for me. You may have a try

TRY THIS

public void findAndSetFont(){
        getActionBar().setTitle("SOME TEST TEXT");
        scanForTextViewWithText(this,"SOME TEST TEXT",new SearchTextViewInterface(){

            @Override
            public void found(TextView title) {

            } 
        });
    }

public static void scanForTextViewWithText(Activity activity,String searchText, SearchTextViewInterface searchTextViewInterface){
    if(activity == null|| searchText == null || searchTextViewInterface == null)
        return;
    View view = activity.findViewById(android.R.id.content).getRootView();
    searchForTextViewWithTitle(view, searchText, searchTextViewInterface);
}

private static void searchForTextViewWithTitle(View view, String searchText, SearchTextViewInterface searchTextViewInterface)
{
    if (view instanceof ViewGroup)
    {
        ViewGroup g = (ViewGroup) view;
        int count = g.getChildCount();
        for (int i = 0; i < count; i++)
            searchForTextViewWithTitle(g.getChildAt(i), searchText, searchTextViewInterface);
    }
    else if (view instanceof TextView)
    {
        TextView textView = (TextView) view;
        if(textView.getText().toString().equals(searchText))
            if(searchTextViewInterface!=null)
                searchTextViewInterface.found(textView);
    }
}
public interface SearchTextViewInterface {
    void found(TextView title);
}

If you really want it to look more semantic like having the <body> in the middle you can use the <main> element. With all the recent advances the <body>element is not as semantic as it once was but you just have to think of it as a wrapper in which the view port sees.

<html>
    <head>
    </head>
    <body>
        <header>
        </header>
        <main>
            <section></section>
            <article></article>
        </main>
        <footer>
        </footer>
    <body>
</html>

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

int code = 2;
Environment.Exit( code );

To make your formula more readable, you could assign a Name to cell A0, and then use that name in the formula.

The easiest way to define a Name is to highlight the cell or range, then click on the Name box in the formula bar.

Then, if you named A0 "Rate" you can use that name like this:

=(B0+4)/(Rate)

See, much easier to read.

If you want to find Rate, click F5 and it appears in the GoTo list.

You can look up an object's keys and values by either invoking JavaScript's native for in loop:

var obj = {
    foo:    'bar',
    base:   'ball'
};

for(var key in obj) {
    alert('key: ' + key + '\n' + 'value: ' + obj[key]);
}

or using jQuery's .each() method:

$.each(obj, function(key, element) {
    alert('key: ' + key + '\n' + 'value: ' + element);
});

With the exception of six primitive types, everything in ECMA-/JavaScript is an object. Arrays; functions; everything is an object. Even most of those primitives are actually also objects with a limited selection of methods. They are cast into objects under the hood, when required. To know the base class name, you may invoke the Object.prototype.toString method on an object, like this:

alert(Object.prototype.toString.call([]));

The above will output [object Array].

There are several other class names, like [object Object], [object Function], [object Date], [object String], [object Number], [object Array], and [object Regex].

@dapangmao's answer works, but it doesn't give the regular spark RDD, it returns a Row object. If you want to have the regular RDD format.

Try this:

rdd = df.rdd.map(tuple)

or

rdd = df.rdd.map(list)

Check iResign for an easy tool on how to do this!

[edit] after some fudling around, I found a solution to keychain-aware resigning. You can check it out at https://gist.github.com/Weptun/5406993

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

I hope this will help you. Regards, Vivek Singla

It's not called a tag; what you're looking for is called an html attribute.

$('div[imageId="imageN"]').each(function(i,el){
  $(el).html('changes');
  //do what ever you wish to this object :) 
});

The color for your buttons comes from the btn-x classes (e.g., btn-primary, btn-success), so if you want to manually change the colors by writing your own custom css rules, you'll need to change:

/*This is modifying the btn-primary colors but you could create your own .btn-something class as well*/
.btn-primary {
    color: #fff;
    background-color: #0495c9;
    border-color: #357ebd; /*set the color you want here*/
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
    color: #fff;
    background-color: #00b3db;
    border-color: #285e8e; /*set the color you want here*/
}

(Because an ASCII picture is worth a thousand characters.)

An arrow may be a helpful mnemonic, especially since that's almost exactly how it looks in Emacs' dired.

And big picture so you don't get it confused with the Windows' version

Linux:

ln -s target <- linkName

Windows:

mklink linkName -> target

You could also look at these as

ln -s "to-here" <- "from-here"
mklink "from-here" -> "to-here"

The from-here should not exist yet, it is to be created, while the to-here should already exist (IIRC).

(I always get mixed up on whether various commands and arguments should involve a pre-existing location, or one to be made.)

EDIT: It's still sinking in slowly for me; I have another way I've written in my notes.

ln -s (target exists) (link is made)
mklink (link is made) (target exists)

the problem is that you tried to read or write data to realtime database or firestore before the user has be authenticated. please try to check the scope of your code. hope it helped!

How about using os.kill? See the docs here: http://docs.python.org/library/os.html#os.kill

Your current directory does not has the write/create permission to create kivy directory, thats why occuring this problem.

Your current directory give 777 rights and try it.

sudo chmod 777 DIR_NAME
cd DIR_NAME
git clone https://github.com/mygitusername/kivy.git

Preferences can either be set in code or can be found in res/xml/preferences.xml. You can read more about preferences on the Android SDK website.

You can also pass events down into child components with something like this:

<CustomComponent
    @keyup.enter="handleKeyUp"
/>

...

<template>
    <div>
        <input
            type="text"
            v-on="$listeners"
        >
    </div>
</template>

<script>
export default {
    name: 'CustomComponent',

    mounted() {
        console.log('listeners', this.$listeners)
    },
}
</script>

That works well if you have a pass-through component and want the listeners to go onto a specific element.

The problem is, you need a xsd schema for packages.config.

This is how you can create a schema (I found it here):

Open your Config file -> XML -> Create Schema

This would create a packages.xsd for you, and opens it in Visual Studio:

In my case, packages.xsd was created under this path:

C:\Users\MyUserName\AppData\Local\Temp

Now I don't want to reference the packages.xsd from a Temp folder, but I want it to be added to my solution and added to source control, so other users can get it... so I copied packages.xsd and pasted it into my solution folder. Then I added the file to my solution:

1. Copy packages.xsd in the same folder as your solution

2. From VS, right click on solution -> Add -> Existing Item... and then add packages.xsd

So, now we have created packages.xsd and added it to the Solution. All we need to do is to tell the config file to use this schema.

Open the config file, then from the top menu select:

XML -> Schemas...

Add your packages.xsd, and select Use this schema (see below)

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

After following the first and second steps mentioned in the hcpl's answer in the same thread, we added , '*.aar'], dir: 'libs' in the our-android-app-project-based-on-gradle/app/build.gradle file as shown below:

...

dependencies {
       implementation fileTree(include: ['*.jar', '*.aar'], dir: 'libs')

...

Our gradle version is com.android.tools.build:gradle:3.2.1

Sometimes you don't need deep merge, even if you think so. For example, if you have a default config with nested objects and you want to extend it deeply with your own config, you can create a class for that. The concept is very simple:

function AjaxConfig(config) {

  // Default values + config

  Object.assign(this, {
    method: 'POST',
    contentType: 'text/plain'
  }, config);

  // Default values in nested objects

  this.headers = Object.assign({}, this.headers, { 
    'X-Requested-With': 'custom'
  });
}

// Define your config

var config = {
  url: 'https://google.com',
  headers: {
    'x-client-data': 'CI22yQEI'
  }
};

// Extend the default values with your own
var fullMergedConfig = new AjaxConfig(config);

// View in DevTools
console.log(fullMergedConfig);

You can convert it to a function (not a constructor).

You shouldn't need to know the index in most circumstances. You can do this:

my @arr = (1, 2, 3);
foreach (@arr) {
    $_++;
}
print join(", ", @arr);

In this case, the output would be 2, 3, 4 as foreach sets an alias to the actual element, not just a copy.

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

Using new api fetch:

const dataToSend = JSON.stringify({"email": "[email protected]", "password": "101010"});
let dataReceived = ""; 
fetch("", {
    credentials: "same-origin",
    mode: "same-origin",
    method: "post",
    headers: { "Content-Type": "application/json" },
    body: dataToSend
})
    .then(resp => {
        if (resp.status === 200) {
            return resp.json()
        } else {
            console.log("Status: " + resp.status)
            return Promise.reject("server")
        }
    })
    .then(dataJson => {
        dataReceived = JSON.parse(dataJson)
    })
    .catch(err => {
        if (err === "server") return
        console.log(err)
    })

console.log(`Received: ${dataReceived}`)                

If you don't have the option to delete the already existing file in the new location, but still need to move and delete from the original location, this renaming trick might work:

string newFileLocation = @"c:\test\Test\SomeFile.txt";

while (File.Exists(newFileLocation)) {
    newFileLocation = newFileLocation.Split('.')[0] + "_copy." + newFileLocation.Split('.')[1];
}
File.Move(@"c:\test\SomeFile.txt", newFileLocation);

This assumes the only '.' in the file name is before the extension. It splits the file in two before the extension, attaches "_copy." in between. This lets you move the file, but creates a copy if the file already exists or a copy of the copy already exists, or a copy of the copy of the copy exists... ;)

Create a small utility function like:

def date(datestr="", format="%Y-%m-%d"):
    from datetime import datetime
    if not datestr:
        return datetime.today().date()
    return datetime.strptime(datestr, format).date()

This is versatile enough:

• If you don't pass any arguments it will return today's date.
• There's a date format as default that you can override.
• You can easily modify it to return a datetime.

the target = _blank is will open in new tab or windows based on browser setting.

To force a new window use javascript onclick all three parts are needed. url, a name, and window width and height size or it will just open in a new tab.

<a onclick="window.open('http://www.starfall.com/','name','width=600,height=400')">Starfall</a>

This is for <object> SVG and className is .svgClass

<object class="svgClass" type="image/svg+xml" data="image.svg"></object>

So JavaScript code is like this:

// change to red
    document.querySelector(".svgClass").getSVGDocument().getElementById("svgInternalID").setAttribute("fill", "red")

To change svgInternalID you have to open SVG file which is plain .txt (ie image.svg) and edit it

<path id="svgInternalID"

Even though this is fairly an old question, I have my 2 cents to share.

You can download the repo as tar.gz as well

Like the zipball link pointed by various answers here, There is a tarball link as well which downloads the content of the git repository in tar.gz format.

curl -L http://github.com/zoul/Finch/tarball/master/

A better way

Git also provides a different URL pattern where you can simply append the type of file you want to download at the end of url. This way is better if you want to process these urls in a batch or bash script.

curl -L http://github.com/zoul/Finch/archive/master.zip

curl -L http://github.com/zoul/Finch/archive/master.tar.gz

To download a specific commit or branch

Replace master with the commit-hash or the branch-name in the above urls like below.

curl -L http://github.com/zoul/Finch/archive/cfeb671ac55f6b1aba6ed28b9bc9b246e0e.zip    
curl -L http://github.com/zoul/Finch/archive/cfeb671ac55f6b1aba6ed28b9bc9b246e0e.tar.gz

curl -L http://github.com/zoul/Finch/archive/your-branch-name.zip
curl -L http://github.com/zoul/Finch/archive/your-branch-name.tar.gz

apt-get install python-setuptools python-pip

or

you'd also want to install the python packages...

For consistency with form fields across browsers we use : box-sizing: border-box

button, checkbox, input, radio, textarea, submit, reset, search, any-form-field {
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
}

This looks cool.

-moz-box-shadow: 0 0 5px #999;
-webkit-box-shadow: 0 0 5px #999;
box-shadow: 0 0 5px #999;

In IMPALA, not having order in the GROUP_CONCAT can be problematic, over at Coders'Co. we have some sort of a workaround for that (we need it for Rax/Impala). If you need the GROUP_CONCAT result with an ORDER BY clause in IMPALA, take a look at this blog post: http://raxdb.com/blog/sorting-by-regex/

Other way to get the minor version is:

SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'

It is always better to close the database/resource objects after usage. Better close the connection, resultset and statement objects in the finally block.

Until Java 7, all these resources need to be closed using a finally block. If you are using Java 7, then for closing the resources, you can do as follows.

try(Connection con = getConnection(url, username, password, "org.postgresql.Driver");
    Statement stmt = con.createStatement();
    ResultSet rs = stmt.executeQuery(sql);
) {

    // Statements
}
catch(....){}

Now, the con, stmt and rs objects become part of try block and Java automatically closes these resources after use.

The answer is no.

Incorrect

.class {
    background-color: none; /* do not do this */
}

Correct

.class {
    background-color: transparent;
}

background-color: transparent accomplishes the same thing what you wanted to do with background-color: none.

In order to keep track of dependency issues, I like to use the conda installer, which simply boils down to:

conda install openpyxl

All the answers above are correct, but when I use windows and disable the Prettier ESLint extension rvest.vs-code-prettier-eslint the issue will be fixed.

To run your_command as a subprocess in a different directory, pass cwd parameter, as suggested in @wim's answer:

import subprocess

subprocess.check_call(['your_command', 'arg 1', 'arg 2'], cwd=working_dir)

A child process can't change its parent's working directory (normally). Running cd .. in a child shell process using subprocess won't change your parent Python script's working directory i.e., the code example in @glglgl's answer is wrong. cd is a shell builtin (not a separate executable), it can change the directory only in the same process.

Suppose you have a list call it a={1,2,3,4,5} Now if you want to print the list in reverse then simply use the following code.

a.reverse
for i in a:
   print(i)

I know you asked using range but its already answered.

^ outside of the character class ("[a-zA-Z]") notes that it is the "begins with" operator.
^ inside of the character negates the specified class.

So, "^[a-zA-Z]" translates to "begins with character from a-z or A-Z", and "[^a-zA-Z]" translates to "is not either a-z or A-Z"

Here's a quick reference: http://www.regular-expressions.info/reference.html

To add to Sweko's point:

The reason why the cast

var listOfX = new List<X>();
ListOf<Y> ys = (List<Y>)listOfX; // Compile error: Cannot implicitly cast X to Y

is not possible is because the List<T> is invariant in the Type T and thus it doesn't matter whether X derives from Y) - this is because List<T> is defined as:

public class List<T> : IList<T>, ICollection<T>, IEnumerable<T> ... // Other interfaces

(Note that in this declaration, type T here has no additional variance modifiers)

However, if mutable collections are not required in your design, an upcast on many of the immutable collections, is possible, e.g. provided that Giraffe derives from Animal:

IEnumerable<Animal> animals = giraffes;

This is because IEnumerable<T> supports covariance in T - this makes sense given that IEnumerable implies that the collection cannot be changed, since it has no support for methods to Add or Remove elements from the collection. Note the out keyword in the declaration of IEnumerable<T>:

public interface IEnumerable<out T> : IEnumerable

(Here's further explanation for the reason why mutable collections like List cannot support covariance, whereas immutable iterators and collections can.)

Casting with .Cast<T>()

As others have mentioned, .Cast<T>() can be applied to a collection to project a new collection of elements casted to T, however doing so will throw an InvalidCastException if the cast on one or more elements is not possible (which would be the same behaviour as doing the explicit cast in the OP's foreach loop).

Filtering and Casting with OfType<T>()

If the input list contains elements of different, incompatable types, the potential InvalidCastException can be avoided by using .OfType<T>() instead of .Cast<T>(). (.OfType<>() checks to see whether an element can be converted to the target type, before attempting the conversion, and filters out incompatable types.)

foreach

Also note that if the OP had written this instead: (note the explicit Y y in the foreach)

List<Y> ListOfY = new List<Y>();

foreach(Y y in ListOfX)
{
    ListOfY.Add(y);
}

that the casting will also be attempted. However, if no cast is possible, an InvalidCastException will result.

Examples

For example, given the simple (C#6) class hierarchy:

public abstract class Animal
{
    public string Name { get;  }
    protected Animal(string name) { Name = name; }
}

public class Elephant :  Animal
{
    public Elephant(string name) : base(name){}
}

public class Zebra : Animal
{
    public Zebra(string name)  : base(name) { }
}

When working with a collection of mixed types:

var mixedAnimals = new Animal[]
{
    new Zebra("Zed"),
    new Elephant("Ellie")
};

foreach(Animal animal in mixedAnimals)
{
     // Fails for Zed - `InvalidCastException - cannot cast from Zebra to Elephant`
     castedAnimals.Add((Elephant)animal);
}

var castedAnimals = mixedAnimals.Cast<Elephant>()
    // Also fails for Zed with `InvalidCastException
    .ToList();

Whereas:

var castedAnimals = mixedAnimals.OfType<Elephant>()
    .ToList();
// Ellie

filters out only the Elephants - i.e. Zebras are eliminated.

Re: Implicit cast operators

Without dynamic, user defined conversion operators are only used at compile-time*, so even if a conversion operator between say Zebra and Elephant was made available, the above run time behaviour of the approaches to conversion wouldn't change.

If we add a conversion operator to convert a Zebra to an Elephant:

public class Zebra : Animal
{
    public Zebra(string name) : base(name) { }
    public static implicit operator Elephant(Zebra z)
    {
        return new Elephant(z.Name);
    }
}

Instead, given the above conversion operator, the compiler will be able to change the type of the below array from Animal[] to Elephant[], given that the Zebras can be now converted to a homogeneous collection of Elephants:

var compilerInferredAnimals = new []
{
    new Zebra("Zed"),
    new Elephant("Ellie")
};

Using Implicit Conversion Operators at run time

*As mentioned by Eric, the conversion operator can however be accessed at run time by resorting to dynamic:

var mixedAnimals = new Animal[] // i.e. Polymorphic collection
{
    new Zebra("Zed"),
    new Elephant("Ellie")
};

foreach (dynamic animal in mixedAnimals)
{
    castedAnimals.Add(animal);
}
// Returns Zed, Ellie

You have a class on your CSS that is overwriting your width and height, the class reads as such:

.postItem img {
    height: auto;
    width: 450px;
}

Remove that and your width/height properties on the img tag should work.

The difference is that concatenate will flatten the resulting list, whereas append will keep the levels intact:

So for example with:

myList = [ ]
listA = [1,2,3]
listB = ["a","b","c"]

Using append, you end up with a list of lists:

>> myList.append(listA)
>> myList.append(listB)
>> myList
[[1,2,3],['a',b','c']]

Using concatenate instead, you end up with a flat list:

>> myList += listA + listB
>> myList
[1,2,3,"a","b","c"]

1. Open Visual Studio Code terminal (Ctrl + `)

2. Write the Git clone command. For example,

   git clone https://github.com/angular/angular-phonecat.git
   

3. Open the folder you have just cloned (menu File → Open Folder)

   

Either remove the DEFINER=.. statement from your sqldump file, or replace the user values with CURRENT_USER.

The MySQL server provided by RDS does not allow a DEFINER syntax for another user (in my experience).

You can use a sed script to remove them from the file:

sed 's/\sDEFINER=`[^`]*`@`[^`]*`//g' -i oldfile.sql

• Just uninstall the previous ADT.
• Go to menu Help ? About Eclipse ? Installation Details
• Uninstall all plugins which Id start with com.android.ide
• Install ADT again from the update site.

In my case, the problem was another. I was trying convert lists of lists of int to array. The problem was that there was one list with a different length than others. If you want to prove it, you must do:

print([i for i,x in enumerate(list) if len(x) != 560])

In my case, the length reference was 560.

You can also call:

navigationView.setCheckedItem(id);

This method was introduced in API 23.0.0

Example

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      tools:ignore="UnusedIds">

    <group
        android:id="@+id/group"
        android:checkableBehavior="single">
        <item
            android:id="@+id/menu_nav_home"
            android:icon="@drawable/ic_home_black_24dp"
            android:title="@string/menu_nav_home" />
    </group>
</menu>

Note: android:checkableBehavior="single"

You can see memory usage by executing this code in your terminal:

$ watch -n2 free -m
$ htop

<form method="post" name="myForm" id="myForm">

replace with above form tag remove action from form tag. and set url : "check.php" in ajax in your case first it goes to jQuery ajax then submit again the form. that's why it's creating issue.

i know i'm too late for this reply but i think it would help.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

May be this wont be a valid argument. but if we increment the value of a const variable inside a function compiler will give us an error: "error: increment of read-only parameter". so that means we can use const key word as a way to prevent accidentally modifying our variables inside functions(which we are not supposed to/read-only). so if we accidentally did it at the compile time compiler will let us know that. this is specially important if you are not the only one who is working on this project.

Similar to Howard's answer but a bit more efficient:

def my_func(low, up, leng):
    step = ((up-low) * 1.0 / leng)
    return [low+i*step for i in xrange(leng)]

for numerical solution, you can use fsolve:

http://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.fsolve.html#scipy.optimize.fsolve

from scipy.optimize import fsolve
import math

def equations(p):
    x, y = p
    return (x+y**2-4, math.exp(x) + x*y - 3)

x, y =  fsolve(equations, (1, 1))

print equations((x, y))

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender ! 
[1] 8
[1] 9
[1] 10

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

To read a particular date from range EJ_PAYDATES_2021 (index is next to the last "1")

=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,1,1)  // Jan
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,2,1)  // Feb
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,3,1)  // Mar

This allows reading a particular element of a range [0] etc from another spreadsheet file. Target file need not be open. Range in the above example is named EJ_PAYDATES_2021, with one element for each month contained within that range.

Took me a while to parse this out, but it works, and is the answer to the question asked above.

You just change the code like this

$("replies").text(parseInt($("replies").text(),10) + 1);

The HTC devices have the PCSII.apk which allow them to select usb connect mode. For your device, you can set it manually:

Use SQLite Editor to open /data/data/com.android.providers.setting/databases/settings.db

open table secure

turn settings starting with mount_ums_ to 0, then restart devices.

UPDATE: If it still doesn't work, try turning on debug mode.

you can use below command,

mongod --dbpath=D:\home\mongodata

Another case for new is what I call Pooh Coding. Winnie the Pooh follows his tummy. I say go with the language you are using, not against it.

Chances are that the maintainers of the language will optimize the language for the idioms they try to encourage. If they put a new keyword into the language they probably think it makes sense to be clear when creating a new instance.

Code written following the language's intentions will increase in efficiency with each release. And code avoiding the key constructs of the language will suffer with time.

EDIT: And this goes well beyond performance. I can't count the times I've heard (or said) "why the hell did they do that?" when finding strange looking code. It often turns out that at the time when the code was written there was some "good" reason for it. Following the Tao of the language is your best insurance for not having your code ridiculed some years from now.
